THANK YOU! I've been wanting just this kind of utility for some time now, but just never got around to doing it. I'll be using it on a regular basis -- in fact, I'll supplement my copy to work/report on any number of columns in one run (e.g. in addition to the "-f" option, I could use something like "-c 1,3-5,e,-2" to get stats on columns 1, 3, 4, 5, the last column, and the column that's two over from the last one).
